I have not personally tried this but 3 members of my family are using these eye drops! They are feeling a significant change in their eyesight, although the result may vary from person to person! It may take a long to have a perfect vision if you're eyesight is too low or you're suffering from some eye illness!
Another thing that is subjective and I don't like is the doctor will break your eyeglasses in front of you, and if you don't break them they won't give you eye drops! My cousin went to this place From Delhi and came back with blind eyes due to no eyewear 🤣
For your help, I'm adding the contact details...
